Watch network communications or capture login credentials.Identify problems before users do using proactive analysis.Verify by seeing the actual traffic such as protocols used, port and protocol numbers, header types, addresses, payloads, and more.Gain insight about who or what is consuming the network resources and discover latency details.Capture and analyze frames and packets so you can identify what’s really happening on your networks.In general, it can be used to analyze network protocols.To get more specific, I’ll list some uses here: Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998.” What is Wireshark used for?On the surface level, network administrators use it to troubleshoot network problems, network security engineers use it to examine security problems and developers use it to debug protocol implementations. Not to mention, it offers a wide range of capabilities to those who utilize it.According to the Wireshark website, “It lets you see what’s happening on your network at a microscopic level and is the de facto standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Those with the ability to use this tool have become a highly demanded. Why is Wireshark the best?In the past, packet analyzers were very expensive or proprietary, but Wireshark has changed that. Essentially, Wireshark can decode most well-known protocols. Without it, understanding a network communication exchange would be almost impossible.As a refresher, the network protocol is comprised of 7 layers, of which Wireshark deals with 2 through 7. What is a network packet analyzer?A network packet analyzer (also known as a network analyzer, protocol analyzer or packet sniffer) is a computer program or piece of computer hardware that can intercept and log traffic that passes over a digital network or part of a network.You could think of a network packet analyzer as a measuring device used to examine what’s going on inside a network cable. Sure, it’s important to be able to configure a TCP/IP network, but understanding the inner workings of a network can set you apart as an in-demand network analyst.

Being familiar with this popular tool can help you stand out on your resume, or can help you go further in your current IT role as it has plenty of benefits for users.“With more than 500,000 downloads a month, the IT industry has embraced Wireshark as the go-to tool for network troubleshooting, optimization, and security,” says TechTarget. P.s when I check for the SNI, only 1 SNI will be ever shown and it's the proxy server's address. This is what I see when I manually open up a TLS 1.3 packet. There are only TLS 1.1 (rarely), TLS 1.2, TLS 1.3 and TCP packets. So how is this possible? am I missing something obvious? In Wireshark, I've tried these filters but no result is shown, after using each filter, I tried reconnecting to the proxies and opened a bunch of websites but still no result came up. my goal is to find out exactly what sensitive and identifiable data is leaving my router after using this proxy, emphasizing on the certificate used in securing the connection. I'm testing a new proxy and monitoring the connection using Wireshark, but I'm not seeing any certificate at all.
